HP Color LaserJet 5 and 5M Printers - Poor Print Quality / Banding on the Internal Demo Page
ISSUE: Print quality degradation or banding is detected when printing an internal demo page.
SOLUTION: Clean both of the corona wires in the printer. This user maintenance should be performed by moving the sliders in a slow motion. Fifteen to twenty seconds should elapse from the moment the slider begins moving until it has been pushed the length of the wire. The same amount of time should be used to slide it back across and into the storage position.
SUMMARY: The exaggerated slowness of the slider movement dissipates charges built up on the corona wire more effectively than a quick motion. Dissipating the charges may restore print quality.
